WHEEL-RIM.

Application filed January 7, 1916.

To all whom it may concern Be 't known that l,-l* u.\xt'is A. Dorms, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois. have invented certain new'and use-- fill Improvements in. ;"\heel-Rims. of which i the following is a specifieatioi'i.

My inrent ion relates to rims for. securing rubber tires and the like, on vehicle wheels. and has for its object. the provision of a simple and eliicient rim of. the character mentioned, adapted to secure a tire to a wheel, where tire and wheel are of sizes ditferent than that intended to be used together. Other objects will appear hereinafter.

An embodiment of my invention is shown in the accon-ipanying drawing, forming a part of this specification and in which- Figures 1, 2, and are transverse sections taken through a felly, folly band and tire rim, embodying my invention. In each of the three figures, the adapting means between the flanges of the felly band and tire rim, is slightly modified from the other' figures.

In many vehicles, and particularly automobiles, the tires on the front wheels are smaller than the tires on the rear wheels. For instance, some automobiles have tires thirty inches in diameter and three inches in thickness on their front. wheels and thirty inches in diameter and three and one-half inches in thickness on their rear wheels. This arrangement necessitates two different sizes of wheels, the rear wheels being slightly smaller than the front wheels.

My invention has tofido with providing means for filling in the space between a rim I and tire on the smaller wheel. It often happens that wheels of the same size are used all around on a vehicle, such as an auto1no bile, and tires of smallenthickness used on the front wheels. hen this is done, it is necessary to provide means for filling in the space between the rims holding'the. tires of the front Wheels and the 'felly bands of said Wheels. My invention applies to this latter condition also. The improvement may also be applied when it. is desired to use larger tires on a Wheel than that ordinarily intended to be used on such wheel. I

Referring more particularly to the draW- ing, ineach of the figures I have shown a section through a felly, 'felly band and tire rim of a vehicle Wheel, such as an automobile wheel. each figure, the folly 5, is pro- Specifieation of Letters Patent.

vided with a'felly band 6, shrunk onto the wood felly 5, in the usual manner well known in the wheel making art. At one of the edges of the telly band 6, is an integral flange 7, which is adapted to assist in holding the tire'rim in position on the wheel. At

the other edge of the fell) band (i, is a detachable flange S. which is adapted to cooperate with the flange 7, to hold the tire rim in position on the wheel. The flange 8, is provided with ears 9, one of which is shown. The ear 9, is perforated and a bolt 10, passed therethrongh. and through the telly 5, and threaded in a nut 11, as clearly indicated. The nut 11, is preferably provided with a shoulder 1'2. to prevent its turning when the bolt is turned to adjust the flange 8 to its operative position, or when it is loosened from its operative position.

The rim holding surfaces 13, of the flanges 7 and 8, are preferably conical and tapering toward each other, to provide means for holding the tire rim between the flanges, as

.clearly indicated. The parts already specifically described, are old and Well knownin the automobile wheel manufacturing art, and no claim is made herein thereto.

My invention consists in providing means adapted to engage the flanges 7 and 8, and position the tire rim 14 concentric with the folly band. In Fig. 1, the tire rim 1 1, is the conventional clencher rim, having an annular band 15 secured thereto by fmeans of rivets 16, two only being shown. At each edge of the band 15, is an adapting member 17', preferably integrally with the band 15, and shaped to fit the surfaces 13, of the flanges 7 and 8. In Fig. 2, the flange en-.

of the tire rim, as clearly indicated in this figure. In this form, the tire rim 21 and adapting members 20, are allformed from a single piece of sheet metal.

While I have illustrated and described' the .preferred form of construction of my invention, I do not desire to be limited to the precise details set forth, but, desire to avail myself of such variations and changes as come within the scope of the appended claims.

I claim l. A deinonntable rim for vehicle wheels comprising a ring shaped in cross-section similar to the cross section of an I-beam, the stem portion of the I forming a circumferential tire rim. the outer portions of the cross bars of'the I forming tire-clai'nping flanges and the inner portions of the cross bars forming bearing surfaces b means of which the rim is clamped to the wheel.

2. In combination. a tire rim for vehicle wheels comprising a main web portion and integral cross webs at each edge of said main web portion. the outer edges of said cross webs being shaped to engage a pneumatic tire and the inner edges of said cross webs being bent inwardly to form beveled surfaces by means of which said 'rini may be clamped to a vehicle wheel.

3. In combination. a vehicle wheel. a felly rim surrounding said wheel and having relatively movable outwardly inclined flanges extendin from opposite edges of the, periphery t ereof, a detachable rim for increasing the diameter of said-wheel, said rim comprising a main web arranged to extend around said wheel, cross webs at the lateral edges of said main web and forming with said main web a rim having a cross-sew tional shape like the cross-section of an I-beani. the outer edges of said cross webs being shaped to engage a tire to hold it in place on said detachable rim and the inner edges of said cross webs having their outer surfaces beveled inwardly to fit between the
